Generalized Eruptive Syringoma in a Nigerian Woman: A Case Report and a Brief Literature Review.

Generalized eruptive syringomas are a very rare variant of syringoma which appear on the chest, neck, abdomen, upper and lower arms, thighs, legs and back. They often affect adolescent or post-adolescent females, although cases have been described in children and older adults. Generalized eruptive syringomas are mostly sporadic but familial cases, and those associated with eczematous skin conditions, solid organ transplants, renal cell carcinoma and some genodermatoses have also been reported. Although eruptive syringomas may resemble cutaneous mastocytosis, disseminated granuloma annulare, eruptive xanthomata, steatocystoma multiplex, eruptive velus hair syndrome, verruca plana and other skin conditions clinically, the histological appearance characterized by upper dermal epithelial cords with a tendency to ductule formation and tadpole extension of outer epithelial layer is diagnostic. We report the case of a 20-year-old Nigerian woman with generalized eruptive syringoma.
